Jan-Erik,
     That is what I am doing right now. Ok! I have the Reset and Gate=20
pins working. I commented out the delay calls and the other commands.=20
The only thing that I am doing right now is just turning the Reset and=20
the Gate on and off. I have two square waves running at 571KHz. This is=20
correct. So it is the 16F690 Timer1 and interrupt code that I can't get=20
working.
Thanks,
rich!

     This is from the datasheet.
         PORTC    0b76543210 these are the pins.
                          0b00001000 this is DP1.
                          0b00001010 this is DP1 and Reset.
                          0b00001001 this is DP1 and Gate.
